The present invention has been illustrated Y in connection with a carhaving a main door and a supplementary door in the side wall thereof.When a door openin ofordinary width .is required the main oor only isopened', the .supplementary door remaining in fixed position.Thesupplementary door may be provided with a movable door jamb, saiddoor jamb being fixed to or detached from saidsupplementarydoor, aspreferred.A VVhen'a doorway of extraordinary width is required the maindoor, the supplementary door and said door jamb are moved doorway.

Referring first to Figures land 2, the car wall is indicated by thenumeral 1, the side plate is indicated by the numeral 2, and the sidesill 'isindicated b the numeral 3. The door jambs 1-4' de 'ne a widedoorway,

intermediate of the width of which is thel movable door jamb 5, whichmay be moved longitudinally of the car when it is desired to provide anunobstructed doorway of rel .atively great width. Movable door jambedoor. These doors may be top hung or bottom hung, the manner .of hangingbeing independent of the p resent invention. According to theillustrated embodimentof the 0 present' invention,- thev supplementarydoor 7 is secured to the movable jamb 5. Said movable jamb in theillustrated embodiment compr1ses an angle 8 of structural steel, the

reentrant angle of which may receive a tim-V ber 9, constituting anailing strip to which boards may be conveniently nailed when it is.desired-to use the car for the carryingv of grain or other lading inrelatively small particles. From an inspection of Figure 2 it will bevnoted that the movable jamb 5 is provided with a Z-bar 10 forming apocket for receiving the edgeo'fthe main door 6. Arranged adjacent tothe right-hand jamb 4 is a Z-bar 11 provided with an angle 12 having aflange for receiving a hooked over edge portion of the main door 6. Themain door 6 fm'ay be provided with the hingedv member 14 for engagementwith the hasp 14 carried by the movable jamb 5. The slidable retainingmember 14 is adapted to securely hold the hinged portion 14 in lockingrelationship with the hasp 14.

Steel doors have been provided in the past, but in `vso far asvapplicants are aware saidl doors' have not been entirely satisfactory.Steel doors have been provided made of members which may be fabricatedonly under rather special conditions, so that repairs have be'en verycostly. According to the ypresent invention, each door is provided atitsv margins with rolled structural steel shapes whlch are purchasablein the open market. Said marginal members are -very sturdy and arepositioned to take the worst of the shocks encountered in service.Conout of clos-ing relationship with thel nected to said marginalmembers are a-plurality of steel members, all of which may be swedgedand machined when cold, so that l `right-hand margin of the door 6 assaid door is viewed in Figure 4 is defined by the W-bar 18. It will benoted that one leg, indicated by the numeral'19, of the W-bar 18 isswedged inwardly forthe purposeof providing'a hook which is adapted to-fit over the angle 12 carried by the stationary door j amb 4. The

structural steel. members 15', 16, 17 and 18 are riveted together toprovide a rectangular frame, said members having-certain of theirflanges crimped slightly at the corners of said frame to permit saidstructural steel members to present plane surfaces on both sides of saidframe. v

Referring to Figure 8, it will be noted that the structural steel member16 has lriveted theretothe swedged steel member 20. A

Having in mind that the right-hand sideof each of Figures 7 and 8indicates the outside of the car, while the' left-hand side of each ofsaidl figures indicates the insideof the car, it will be noted that theswedged steel member 20 is positioned relative to the` structural steelmember 16 so as to shed rain and other forms of precipitation. Saidswedged steel member 2O is bent inwardly toward theA rear of the door,that is-toward the interior of the car, and provides a flange 21, whichflange 21 extends substantial parallel with the planes provided by therinner and outer sides of the frame provided by the structural steelmembers 1-5, 16, 17

`and 18. Said flange 21 is secured to the panel 22, which panel ispositioned on the inner side of the flange 21. The swedged steel member2O is located midway of the width of the door, but stops short of thecorners of said door. Gussets 23-23 are provided at the two corners,which have overlapping relationshipv with`the swedged steel member 20.Said gussets 23-23 areA also swedged to provide flanges 24-24 located insubstantially the same plane-as the flangel l21, overlapping flanges,being 'crimped to y Apermit the positioning of flanges 21 and 24-24 insubstantially the same plane. Said gussets are also riveted to theinnerside of the frame provided by the structural steel members 15, 16, 17and18.l

Located below the panel 22 is the channel member 25. .Said channelA 25has the upper mamie flange 26 secured to the-inner side of thel asindicated by the numeral 28, which flange 28 is riveted to the outerlsurface of the panel 27. Located at the lower edge of the panel 27 isthe .channel 29, which has the upper flange 30 secured to the innersurface of panel 27, being located between said panel 27 and the panel31. The lower flange 32 of the channel 29 is secured to the outerysurface of the panel 31. The lower edge of the panel 31 has Securedtheretothe swedged steel member 33, which swedged steel member 33 hasthe flange 34 located'on theinner surface of the panel 31. Said swedgedsteel member 33 is riveted to the structural steel member 17.

Arranged at the two sides of the door 6 are the two gusset plates 35-35,which have overlapping relationship with the gussets 2323 and thechannel member 25. f Said ygussetsb35--35 conform in'cross section attheir extremities tovsaid gussets23-23 and channel member 25 andare'riveted to same as well as being riveted to the panels 22 and 27land to the rolled structural `steel members Positioned at the two endsol the panels 27 and 31 are the gusset plates 36-36, `having extremitiesconforming to the corresponding portions of the gussetplates 35--35 andto thekchannel 29. Said gussets 36--36 are 4riveted to the panels 27 and31, the channel 29 the side structural steel members 15 and 18 and tolower corresponding gusset plates y 23-23, which are identical in shapewithv the upper gusset plates 23-23 referred lto above.l Said lowercorner gusset plates 23- 23 are riveted to theswedved steel member 33,said lower cornergussett" plates an'd lsaid member 33 beingriveted tothe remainder of lthe door to providey a solid job. -It will l .be notedthat the lower structural steel member 17 is cut away to provide spacefor rollers `37-37, which may be rotatably mounted in any preferred way.The pockets in rear of the gusset-s 23, 35 and'36 along the side marginsof the door are closed by the plates 3838. rIhe pockets in rear of thesteel members 2O4 and 33 and j their adjoining'gussets23 are closed byother plates 38-38. Said members 38-38 may be crimped attheiroverlappedgend portions, whereby` the greater extent ofsaid members 38along the four margins of the door may lie in engagement with thestructural steel shapes 15, 16, 17 and 18.

The description of door 6 which appears above will be sufficient for anunderstanding of the construction of door 7. The invention is notlimitedto constructions having a pair of doors on each side of the car,but is :equally applicable to single doors.

ra .rectangular frame made up of It will be noted that the-inside ofeach of the doors issubstantially flat, fthe overlap between adjoiningpanels and wtheir,`

strengthening members necessitating onlya slight divergence vfrom aperfectlyl flat conu dition. The outside of the door with itsreinforcing channelsl ,presents4 a workmanlike appearance, and greatstrength is had'pe i unit 'of Weight byreason of the box girdersprovided by the members20 andf 33, the

channels -25 and 29 and the Vgussets 23,254

and 36, together withfthe backing members jacent to theltwo side marginsoffthe door are identical 1in shape and therefore interchangeable.Thematte'r of manufacture and repair is therefore greatly simplified.

It will) be noted that starting from'the top of each?Y of the doorstheparts -are soy 'overlapped that the members closest to the top ofthecar are lapped on the outside of the member next adjoining at a lowerlevel.
